**7. Interpreting OGTT result: improving reproducibility**

#### **7.1 Considerations when interpreting OGTT result**

When interpreting the result remember that OGTT has variable reproducibility and care should be taken not to over-interpret the results. Use only one criterion, eg WHO criteria, to indicate a diagnosis of IFG, IGT or diabetes. In most cases the results of fasting and 2-hr post-glucose load are enough. Always look for help from local diabetes serves in uncertainty. Refer cases you can not evaluate to endocrinologist for further for assessment. Usually there are no causes of false-positive result when processes are strictly followed. These arts will improve the reproducibility.
